PICTURE-FRAME Specification of Letters Patent.

Application 'lled October 26, 1907. Serial No. 399,373.

Patented Dec. 8, 1908.

To all whom it may concern:

Be it known that I, EDWARD W. CRAIG, a citizen of the United States, residing in Chicago, Cook county, Illinois, have invented certain new and useful Improvements in Picture-Frames, of which the following is a full and correct specification, reference being had to the hereto accompanying drawing, forming apart hereof, and in which- Figure 1 shows a plate or sheet of my material for makin@r my said frames, in elevation, marked ready to be put into shape. Fig, 2 shows a transverse section of Fig. 1 in elevation and shaped into a frame. Fig. 3 shows a fragment of a corner and its back, of my said frame, in plan view. Fig. 4 shows, in plan view, on its rear side, a fragment of my material marked and cut and ready to put into position as shown in Figs. 2 and 3.

ig. 5 shows, in sectional elevation, one side of a frame and a fragment of the back, forming, a part thereof, rovided with a covering.

Like reference etters show like parts throughout.

The obj ect of my invention is to roduce a picture-frame from thin sheets of c ea light and strong material, such as strawoard, wood-veneering and like suitable material, which when veneered with a suitable aper or textile material, which, when ma e according to my construction, may be made to assume the a pearance of either expensive Wood or metdl, or fine gilding or bronzing, and the like. To attain said desirable end I construct my said new picture-frame in substantially the following manner, namely: On a sheet of suitable straw-board a, or cardboard, wood-veneering, or like suitable material, is cemented a sheet a. of strong paper or suitable textile. Said parts, thus prepared, form the stock from which my icture-frames are made. Said materia is then cut to suitable sizes in rectangular forms, and on the back a are then scored four sets of lines 1, 2, 3, and the s uares b', formed by the intersection of the lines 1, and 2, of adjacent sides, cut out, and from the lines 2 2 the ends of the elements or faces c are formed by cutting the mitral lines d, which may be extended to the edge d3 or stopped at the intersection of the line 3 so that the corners d indicated by the broken outlines at the ends of the faces d may be retained for the purpose of increasing the gluing surfaces in lengt The lines, or scores, 1, 2, 3, are cut into the back, or uncovered face of the backing a. When each corner of the said material is cut and scored as shown in Fig. 4 all the elements d are turned inward on their lines 3 as on a hinge, and the faces c are turned in the same direction on their hinge lines 2, and the inner elements b are turned on their hinge lines 1 so as to stand at a right angle to the frame-back a and so that the several parts assume the ositions shown in Figs. 5 and 2; the glue f aving been applied just before the parts are moved to thelr respective positions. We now have a picture frame provided with a back a integral with the frame formed of the vertical sides b and the inclined sides c formed from the middle element held to lace b the outer elements d charged with gquej a hering to the facing a. Over the surface of this so constructed picture frame is then put a suitable finish; this may consist of paper e in imitation of wood 1n its surface and, again, the said frame may be finished in imitation of gold, or bronze and similar ornamental finish. The said frame so constructed having all its parts, including the back integral, all cut from a single piece, forms an exceedingly strong yet very light structure into which a picture may be cemented on the framed or bordered surface of a. The facing a also forms a hinge-element or part on which the frame-elements b, c, d, turn to their places on their hinge-lines 1, 2, 3, and said faces remain integral with each other and the back. The lines b" bf form two sides of a square formed by the intersection of the sets of lines 1, 2; 1, 2, and form the meeting edges of the edge-pieces or faces of the frame-edges b. The fixing-element d is the outer element of the series, and it is the one whichis necessary to hold all the other,

ing it atj to the facing a/ on the back a all as shown, element for element, each in its proper position.

What I claim isz- A picture-frame comprising a back and thereto attached inner7 middle, and outer hinge-connected frame-elements whereof said inner element is vertical to said back,

the middle element inclined from the top of said inner element to said back and the outer 10 element lies against said back and abuts against said inner element.
